Patented Feb. 11, 1941 UNITED vSTATES PATENT OFFICE 5 Claims.

The present invention relates to an improvement in mechanical movements.

While the present device is adaptable to other uses, it is shown hereinas a means for operating a swiveled, non-draft Ventilating window forclosed automobile bodies.

Two forms of the toothed actuating means are shown, these both beingsubstantially equivalent in function, and they both compriseinterrneshed, toothed, reciprocatable actuating means which translatesmotion, from. a primary driving source, to a to and fro operativelydriven means located at right angles to the primary means.

The foregoing function lends itself admirably to manual operation, fromthe inside of an automobile, to operate the Ventilating section of thewindows, for the purpose of opening and closing the ven-tilating Windowsection for ventilating the interior of closed car bodies in a draftlessmanner, in accord with current practice.

The foregoing, and other features of advantage will be apprehended asthe herein description proceeds, and it will be obvious that modicationsmay be made in the structure herein disclosed, without departing fromthe spirit hereof or the scope of the appended claims.

In the drawing,

Fig. 1 is a sectional View taken on line I-I, Fig. 2, looking in theVdirection of the arrows;

Fig. 2 is a perspective View looking at the bottom of the preferred formof structure; and

Fig. 3 is a View in side elevation of a modified form of right angledmotion translating means.

In Figs. 1 and 2, the motion translating means comprises, a preferablymetal angle iron b'ase I, which may formr the frame or sill of thewindow opening in a door, though this detail may be varied, as may otherdetails shown herein.

Gn the inside, adjacent faces of the angle iron base I is slidablylocated a double toothed, right angled, rack element generally denotedby .5, Figs. 1 and 2, said rack being nested or fitted for a limited,reciprocal sliding movement, to and fro in the inside angled seat of theangle iron I, as shown in Fig. 2.

, The rack B comprises a right angled structure, having gear or rackteeth o-n each angled edge so as to provide toothed engagement with twotoothed pinons 4 and 5, which are rotatively and angularly mounted inthe angled webs of the angle iron I, as Vvll be seen in Figs. 1 and 2.Each pinion, 4 and 5, are engaged with their respective toothed portionsof the angled teeth (Cl. i4-422) on the right angled rack element 6,said pinions being rotatively located at right angles to each other inthe webs of the angle iron base I, and each pinion being provided with apreferably, integral shaft, 3A and 2, respectively, whereby the rotationof pinion 4 operates to slide the right angled rack element 6 to' andfro and this rack movement causesk rotaryv movement of the pinion 5.

The stub shaft 2 of pinion 4 has an outer extension which passes throughone leg of the angle iron 6, as best seen in Fig. l, and upon thisextension is Xedly mounted the hub I9 of an operative handle II-I2. Awasher I5 may be mounted upon said extension and a nut I3 may bethreadedly engaged upon the end of shaft 2, to secure the handleassembly in rotative drive assembly with the pinion 4, whereby saidpinion may be rotated to reciprocate rack 6.

The other pinion 5, Fig. 1, also has an extension of its shaft 3, whichis rotatively mounted through the other web of angle base 6. A spacingcollar I4 may be mounted upon the extension of shaft 3, which rotativelypasses up through a frame base plate or strip I5, and a base channelsection I6, the extension of shaft 3 being threadedly engaged by a nutI'I, so as to fixedly secure the base channel section IG, so that whenpinion 5 is rotated, the channel I6 is oscillated on the base plate i5,said plate forming, in some forms of window construction, a xed,non-movable window frame or sill forming member at the bottom. of theventilating window section, Said sill forming member I5 being fixed tothe window frame forming section of the door. Other means foraccomplishingv a structural embodiment for forming a frame and sillforming structure may be utilized.

The Ventilating, oscillatable window, as seen in Figs. 1 and 2 comprisesa glass window pane section I9, which is fixedly mounted in asurrounding metal channel section I8,which in mo-st cases, completelysurrounds the outer edge or contour of the glass pane I9. As noted inFigs. l and 2, the channel I8, at the lower edge of pane I9, ts into thechannel I6, between the flanges thereof, so that any radial movement ofthe channel IB caused by the rotation of shaft 3, acts to swivel pane I9to open or close the pane section I9 and its supporting channel I8. Theupper edge of the pane I8 and its pane I9, may be pvotally supported byan axially located pivot, not shown, but Well known in this art.

Both pinions 4 and 5 are provided with short, integral tit extensions 8and 1, respectively, Figs. 1 and 2, at their external faces, and thesetits are utilized so receive thereon the open ends of a coiled,compression wire spring 9, Fig. 1, whereby to keep both pinions 4 and 5compressively seated against the respective faces of the angle ironwebs. This spring while acting at all times to resiliently maintain saidpinions in their respective operative positions relative to theirrespective rack tooth engagements, also constantly acts, resiliently, toexert the seating pressure on said pinions, during any rotative motiontranslation thereof, as, obviously the spring 9 is resiliently reactingto any rotative action of the pinions 4 and 5.

While spacing rings and collars, have been described in the foregoingdisclosure, obviously, aside from the main motion translationI abovedescribed, modifications, substitutions, or alternative constructionsmay be provided, to suit conditions of local assemblies, withoutdeparting from the main feature of the main idea of the pinion and rightangled rack motion translation means, as above disclosed.

An alternate form of motion translation means is disclosed in Fig. 3,wherein there is shown a skeletonized assembly of two pinions 4 and 5,each provided with shafts 2 and 3, only one shaft 2 being shown, eachpinion having the external stem extensions 'l and 8 as described forFigs. 1 and 2, for the same purpose as described for said latterfigures.

In Fig. 3, however the right angled and toothed motion translating meanscomprises what may be termed a circular, angular rack, having a set ofinternal teeth to engage with pinion 5, and a set of horizontal teeth 2|to engage with the pinion 4. The cross section of this circular toothrack or ring gear is identical with the angular cross section of theangular rack 6 of Figs. 1 and 2, but as shown and constructed in Fig. 3,the rack is circular and endless. The function of the circular rack 6 isidentical withk that described for Figs. l and 2, in that rotativemovement of the pinion 4 causes a right angled motion translation to thepinion 5. Both pinions may be rotatively mounted upon an angle iron basel, and the tits 1 and 8, Fig. 3 may also receivably seat a coiled spring9, for the purpose and function as described for and disclosed in Figs.1 and 2.

In Figs. l and 2, the right angled tooth rack 6, may be of suiiicientlength to permit of the rotation of the ventilation window pane I9 andits appurtenant rotative parts from the closed position to an openposition of approximately ninety degrees from said closed position.

In general operation, as a Ventilating window control, the device asshown in Fig. 1, the nut I3, may be so frictionally tightened as topermit of -easy operation of the handle II--I2, to open or close thewindow section l8|9, but due to the friction thus created by thesecuring means to prevent the closing of the Ventilating window sectionby wind pressure, this being one of the objects of the presentimprovement. Other means may be utilized to provide a means forpreventing window closing reaction by the wind,

when the window is open, but at the same time to permit easy opening orclosing of the Ventilating window section from the inside of the vehicleby the handle Il-I2, and thus the Ventilating Window section iscontrolled by an irreversible geared control for the purpose hereindescribed.

In other uses of the mechanical movement herein disclosed, the structureof Fig. 3 permits of unlimited circular or angular motion so long as thepinion 4 is rotated in either direction.
